Is it possible to play two different tube amp heads at the same time out of one 1960a cab? Mine has the switch on the back to make the cab run in stereo mode and I was curious if it would be possible to use both inputs for independent heads. Of course the impedance would have to be matched (8 ohm - 8 ohm), but I have no idea if it would handle the amp load properly or not. Trying to find out for sure so I can avoid breaking something if it's not possible.
It is possible as long as the amplifiers can run into 8 ohms, put the switch on the back of the cabinet to stereo this splits the cabinet left and right if it is a standard 1960A/B this 150 watts per side at 8 ohms. Plug the two speaker leads from the cabinet one into each of the amplifiers ensuring the amplifiers are set to 8ohms.
